Understanding the Key 3D Printing File Formats

Understanding the various 3D printing file formats is crucial for achieving optimal results. Different file formats serve different purposes, each offering unique advantages depending on the complexity and requirements of the project. This article will introduce and compare the most common 3D printing file types. 1. STL (Standard Tessellation Language) File structure: STL files use triangular meshes to represent the surface of 3D objects. Each triangle is described by its three vertices, which are exp......

3D Printed Keychains: How to Make Them & Creative Ideas

Keychains are small, but they say a lot. They’re not just a way to keep your keys together, they’re a chance to show off personality, brand something, or even make a quick useful tool you’ll actually carry every day. And with 3D printing, you’re not limited to what’s on a shop rack. You can make anything, custom names, clever gadgets, logos, or just cool little designs that could go viral. In this blog, we’ll share some of the best 3D printed keychain ideas that are practical, fun, and worth trying ou......

Best 3D Prints to Sell Right Now: Top Selling Items & Ideas

If you’ve got a 3D printer at home and you’ve been thinking, “Hmm… could I actually make money with this?”, the answer is yes. But here’s the thing: not every cool print idea is a good business idea. Some designs look amazing but take forever to print (and customers won’t pay enough to make it worth it). Others are quick to print but nobody wants to buy them. The sweet spot? Items that are useful, in-demand, quick to produce, and easy to ship. In this guide, I’ll walk you through the most profitable 3......

Can You 3D Print Glass? Alternatives & Real Use Cases

Can you actually 3D print glass? Yes, but with major caveats. While the idea of printing pure glass sounds futuristic, the reality is still experimental and expensive. Most users exploring glass 3D printing are actually working with glass-filled filaments, a practical, polymer-based material infused with glass fibers to improve strength and heat resistance. But for industries where transparency, aesthetics, or heat resilience matter, like medical device prototyping, aerospace ducts, or optical fixture......

G-Code 3D Printing Commands: Tutorial, List & How to Use Them

(Freepik) If you’ve ever peeked insidfe a 3D printer’s sliced file and seen a wall of cryptic letters and numbers, congrats, you’ve met G-code. It’s not flashy. It’s not forgiving. But it’s the language that tells your printer exactly how to bring your model to life, line by line, millimeter by millimeter. Most users never touch G-code because slicers handle it automatically. However, If you're serious about improving your prints, understanding G-code 3D printing isn't optional, it's essential. This i......

Best 3D Printer Extruder: Strongest & Most Reliable Options for 2025

The extruder is the heart of your machine. It’s the part that grips, melts, and precisely feeds filament to create each layer of your model. A weak or unreliable extruder can cause clogs, under-extrusion, and inconsistent prints. But with the best 3D printer extruder, you can dramatically improve print quality, reduce downtime, and expand the types of materials you can use. At JLC3DP, we’ve tested dozens of extruder setups for different printers and materials and learned that a strong, reliable extrud......

Best 3D Printing Material Guide for Every Application

Whether you are an engineer designing functional components or a hobbyist building your next creative project, material choice can make or break your 3D print. Strength, flexibility, heat resistance, and chemical durability all depend on the right pairing of material and technology. In this guide, we break down 3D printing materials into three main application categories: a. Functional Prototypes & Everyday Engineering Parts (FDM Polymers) b. High-Detail Models & Precision Components (SLA Resins) c. I......

SLA vs FDM 3D Printing: Which One’s Right for You?

If you're stepping into 3D printing, whether you're prototyping a product, customizing a part, or just geeking out on high-precision prints, you've probably come across the showdown: SLA vs FDM 3D printing. These two technologies dominate the desktop and industrial scenes, but they’re vastly different in how they work, what they produce, and when to use each. Whether you're a product developer needing fine detail or a manufacturer building quick functional parts, knowing the differences between SLA an......

How Material Jetting 3D Printing Tech Works & When to Use it

Material jetting is one of the most precise and visually detailed 3D printing methods available today. If you imagine how inkjet printers work, layering ink dot by dot, material jetting 3D printing works similarly, but with droplets of photopolymer resin or wax that are cured layer by layer using UV light. This method shines in applications where ultra-smooth surface finish, high accuracy, and color realism are critical. But it’s not for everyone, costs, material options, and durability limitations ke......

JLC3DP Collaborates with Retsetman: Exploring Innovative Mechanical Design with 3D Printing

3D printing technology is widely used in mechanical design, especially in the realization of unique mechanical designs. Through 3D printing, engineers can more flexibly create complex structures and achieve rapid prototyping of high-precision parts, thus accelerating design iterations. The cooperation between JLC3DP and mechanical design blogger retsetman is a typical case. In this cooperation, Retsetman designed two extremely creative projects: a high reduction ratio "nutation swing gear" and a uniqu......

JLC3DP helps CPSdrone explore deepwater mines

During adventure to explore deepwater mines, YouTube blogger CPSdrone built a DIY submarine to try to go deep into flooded uranium mines and record the deepwater scenes with a camera. In this project, JLC3DP, as a key sponsor, provided the submarine with customized 3D printed nylon parts, which use advanced SLS technology to enhance the submarine's design durability and deepwater performance. In CPSdrone's previous waterproof tests on 3D printed objects, JLC3DP also provided bloggers with high-quality......
